fix(first launch backend container crash):

We now wait for the necessary static files to be generated before collecting the static files in the backend.

Fixes #88

backend/waitForFrontend.sh

+#!/bin/bash
+
+# Script to make sure that assets from the frontend have been generated at least
+# once so that the backend container doesn't crash on the first launch.
+
+while [ ! -f `dirname $0`/../frontend/webpack-stats.json ]; do
+    echo "Waiting for frontend static files to be initialized..."
+    sleep 2
+done
+
+echo "Frontend staticfiles are ready (NB: not necessarly up-to-date)."

-**When you launch the project for the first time you'll most likely have the backend container crash due to the lack of some static files. Make sure not to stop the launch process until you see `frontend_1 | ℹ ｢wdm｣: Compiled successfully` in the console. Then you can stop the command (`CTRL+C`) and do `make up`; you shouldn't have issues thereafter.**
